EDWARD F. LALLY, OF NEW YORK, N. Y.

SAFETY-PIN.

Application filed August 8, 1916.

To all whom it may concern:

Be it known, that "I, EDWARD F. LALLY, a citizen of the United States, residing at the city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Safety-Pins, of which the following is a specification.

My invention relates to a new and useful improvement in safety pins, and more particularly to that class of safety pins that are formed from a single piece of wire, and the one end of the wire so bent as to form a guard for the pin point and a catch or retaining means.

An object therefore of my invention is to provide a safety pin preferably made from a single piece of wire having a. guard formed on the end thereof by bending and turning the Wire in certain spaced relationships so that the point of the pin will be protected and so that a special form of guard is formed in that it will direct the pin proper into the guard when forced to its locking position.

Still another object of my invention is to so bend or form the wire that a portion at the one end of the same tends to direct the pin-point into the guard and furthermore acts as a safety device to prevent as far as possible the unfastening of the safety pin other than by intentional pressure.

With these and other objects in view my invention consists in certain new and novel constructions and combinations of parts as will be hereinafter more fully described and pointed out in the claim.

Referring now to the drawings: Figure 1 is a perspective view of the preferred form of my safety pin; Fig. 2 is a detailed elevation of one end of the pin; Fig. 3 is a horizontal section of the same; Fig. 4: is a transverse section of the same; Fig. 5 is a section showing the pin being pressed into the guard; Fig. 6 is a perspective of a modified form of my improved safety pin; Fig. 7 is a transverse section of the same; Fig. 8 is a horizontal section of the same; and Fig. 9 is a further slight modification of my improved safety pin.

Referring now to the drawings (Figs. 1 to 5 inclusive) it will be seen that my improved safety pin is formed preferably of a single piece of wire having a bar or pin proper 1, which is bent on itself as at 2 to afiiord a spring action, and then extends for- Specification of Letters Patent.

wardly forming the upper bar 3. This bar 3 has a loop 1 formed nearly directly above the point of the bar 1, which loop forms a very essential part of my improved pin, and the function of the same will be referred to hereafter. Continuing from the loop 4 is the portion 5, which extends from the plane of the bar 3 downwardly to a point beneath the normal plane of the pin bar 1 and acts as a guard to the point of the pin 1. The wire after being bent downwardly as at 5 is again bent upwardly and outwardly and again downwardly to form the inverted U-shaped loop 6, and as shown extends slightly inwardly as at 7, that is transversely to the axis of the bar 1. The wire continuing from the portion 6 then extends upwardly and forms another inverted U-shaped loop 8 similar to the loop 6 but of course transposed in its position. The inwardly extending portion of the loop 8, that is the portion 9, is so spaced from the inwardly extending portion 7 that there is left just enough space for the bar pin 1 to be forced between the two points of contact 7 and 9 into the lower portion of said loops. The end of the wire at the lower end of the loop 8 is then curled around the lower portion of the part 5. From the above it will be seen that we have a safety pin comprising but a single piece of wire and with a portion of the wire so bent as to form the guard. Referring again to the loop portion 4: it will be seen that this extends downwardly between the two loops 6 and 8, and as shown in Fig. 1, it extends downwardly to a point nearly opposite the two inwardly extending portions 7 and 9. Suppose now the point is in its unfastened or open position, the pin bar 1 will be forced downwardly between the portion 4.- and either the loop 7 or 8, (as shown in Fig. 5) and will be guided in its downward movement by the loop 4. After the bar 1 is in its locked or fastened position any unintentional pressure will in all probability force the pin upwardly, and the pressure would have to be great enough to force it between the two inwardly extending portions 7 and 9. Furthermore the pin would then be forced against the top of the loop 4:, which loop will tend to hold the pin against any further upward movement, it being nearly impossible to force the pin bar 1 out of the loops and beyond the loop 4 unless the pin bar 1 is forced upwardly and with a relatively great lateral pressure. The loop 4 therefore, it will be seen performs the double function of guiding the pin bar 1 and furthermore acting as a limit or stop to the upward movement of the bar 1 unless the same is forced upwardly and with a laterally disposed movement.

Referring now to the form as shown in Fig. 6 it will be seen that the same is nearly identical with the form shown in Fig. 1, but in this instance instead of having one guard portion 5, the same has a double portion such as at 10, which ends at the top of portion 5, and the pin point of the bar 1 centers between the double guard portions 5 and 10.

In Fig. 9 there is shown a slightly modified form wherein the loop 1 in this instance instead of extending only to a point above the portions 7 and 9 extends downwardly into said loops beyond the inwardly extending portions. The pin will function in the same manner, that is the bar 1 will be stopped in any upward movement, and to release the same it will be necessarv to exert a lateral pressure on the same and then an upward pressure.

From the foregoing it will be seen that my safetv pin is exceedinglv simple in its structure, may be made cheaply and easily from a single piece of wire, and that by providing the loop portion -1 directly above the inverted looped U-shaped portions a stop or guard member is provided that will stop the pin in its upward movement unless the same has an intentional lateral movement, and at the same time the same acts as a guide to direct the bar pin 1 into its locked position.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A safety pin consisting of a piece of wire bent upon itself to form an upper bar and a point bar, the upper bar having a loop formed therein and which is disposed toward the free end portion of the point bar, the opposite sides of the said loop lying in planes which are approximately parallel with the longitudinal axes of the said bars, the upper bar being extended from the said loop transversely across the point bar and beyond the free end thereof and the said extended portion being continued into spring loops having at points between their ends inwardlv disposed humps which lie be yond the edges of the first mentioned loop, the second mentioned loops having outwardly disposed upper ends which are disposed transversely across and beyond the sides of the first mentioned loop.

In testimony whereof I affix my signature.
